Analysed five years of margins, ROIC, leverage, cash conversion, and accounting policy, then built two-year forecast statements. FY2025 gross margin remained near 60% and free cash flow reached $2.69bn, while rising inventory days and impairments tempered the acquisition case.

Compared inflation, expectations, unemployment, and GDP around New Zealand’s 1989–92 regime change. Inflation fell from 9.28% to 3.23% as unemployment rose from 5.76% to 9.75%; later stabilisation supported credibility, although concurrent reforms limited clean attribution.

Normalised Lennox’s statements, forecast five years of free cash flow, and compared DCF, peer-multiple, and two-stage dividend models. The blended value was $523.81 per share versus $511.42, while the wide range between methods made valuation sensitivity central to the conclusion.

Built a mean–variance frontier for CMG, ORLY, MNST, and TSLA using five years of weekly data. The lowest attainable probability of earning below 8% was 23.07%, showing that the required sub-20% downside constraint was infeasible for this asset universe.

Synthesised evidence on regulatory certification, rating triggers, and capital-structure responses to examine how ratings can alter funding costs and amplify default risk. Firms rated more favourably by DBRS experienced a nearly 55bp yield reduction after its NRSRO recognition.

Used 252 trading days of S&P 500 and Treasury-bill data to estimate 18.57% annualised volatility and price an at-the-money European call with CRR trees. The illustrative time-varying two-step model produced $256.59 versus $252.20 while relying on ex-post parameters.

Mapped cradle-to-grave impacts, estimated unit economics, and stakeholder risks across materials, manufacture, transport, use, and disposal. Comparative results remain in revision while the functional unit, electricity conversion, transport assumptions, and headline comparisons are recalculated.

Tested 72 mesh configurations to isolate how element shape, order, and density altered stress and displacement estimates in a loaded spanner. Refinement captured 42.9% more peak stress, while quadrilateral meshes produced comparable displacement with approximately 40% fewer elements.

Integrated thermodynamic cycles, renewable-fuel supply, equipment selection, and generation economics into an off-grid island-system design. The model is being rebuilt and independently unit-checked, so no cost-per-kWh result is presented yet.

The model reduced required area from 13.072 to 4.702 m² and tube count from 124 to 45, while raising the heat-transfer coefficient from 200 to 404 W/m²K. Velocity, pressure-drop, and fan-power outputs remain under review.

Combined open-loop system identification, MATLAB/Simulink modelling, and practical PID testing on a water-level rig. The theoretical time constant was 127.2 seconds versus 138 seconds experimentally, an 8.4% difference.

Applied first- and second-law analysis to an R134a vapour-compression cycle to identify where irreversibility concentrated across the system. The COP and exergy balance are being reconciled, so numerical results are not yet published.

Compared steam and organic Rankine-cycle options using published evidence, then assessed n-pentane, HFE-7000, and HFE-7100 against operating constraints. The work separates sourced fluid properties from original calculations rather than presenting one unqualified “best” fluid.

Compared theoretical and measured heat-transfer coefficients under natural and forced convection in a four-person laboratory study. The analysis focuses on how experimental error changed across operating conditions and why uncertainty matters when validating a model.

Recorded horizontal and vertical cantilever deflection at 0°, 30°, and 60° in a four-person experiment. Several vertical results diverged from theory, showing why experimental agreement must be quantified rather than assumed.
